Adaptive Reverberation Absorption using Non-stationary Masking Components Detection for Intelligibility Improvement
G. Zucatelli, R. Coelho
This letter proposes a new time domain absorption approach designed to reduce masking components of speech signals under noisy-reverberant conditions. In this method, the non-stati…
Impulsive Noise Detection for Intelligibility and Quality Improvement of Speech Enhancement Methods Applied in Time-Domain
C. Medina, R. Coelho
This letter introduces a novel speech enhancement method in the Hilbert-Huang Transform domain to mitigate the effects of acoustic impulsive noises. The estimation and selection of…
Effective Acoustic Energy Sensing Exploitation for Target Sources Localization in Urban Acoustic Scenes
M. Alves, R. Coelho, E. Dranka
This letter proposes a new approach to improve the accuracy of the Energy-based source localization methods in urban acoustic scenes. The proposed acoustic energy sensing flow esti…
Objective Human Affective Vocal Expression Detection and Automatic Classification with Stochastic Models and Learning Systems
V. Vieira, R. Coelho, F. Assis
This paper presents a widespread analysis of affective vocal expression classification systems. In this study, state-of-the-art acoustic features are compared to two novel affectiv…
